Carter, Bradford,

In Great Britain April 10,}1937' 10 Claims. (01. 19-84) This invention relates to improvedmeans and apparatus for the extraction of burs from wool and other textile fibers.

:The usual method .of extracting bursis by means of carding machines which comprise a series of what are known as lickers, dividers, and bur removers, the material passing through thesystemj and being finally delivered to what is known as a swift. The lickers, dividers,

and bur removers, with or Without what is known asa Morel? motion, have been arranged in a variety of manners and havebeen driven atvarying speeds, but in every case the devices have followed one another as a unit; Our invention 16 diifers from the usual method in that, instead of the wool'orlike material passing in one course from one lic'ker to the next and so on until the swift is reached, the wool is divided into two streams or paths, one say leading upwards and the -20 other downwards and conducted forward till the two streams again meet and are then delivered to the swift'in convenient manner. Thisarrange ment enables both short and long wools to be efficiently burred without theflcollection with the 25 bur of an'excessive amount of'wool.

The before mentioned division of the wool entails a rte-arrangement of the lickers, dividers tightening rollers and bur rollers, with addition to 'orsubtraction fromthe usual numbers there- 30" of, and whilst this arrangement may vary, we v hereinafter describe'an arrangement suitable for attaining our object.

By'dividing the material-into two parts it will readily be understood that the rollers ,on which 35 burring takes place are more lightly loaded than is the case where the wool orlike is not so divided and consequently the bur rollers act more efiiciently.

It is well known that the capacity of a carding 40 engine is limited according to the capacity of the ,main burring rollers, therefore by having or reducing the amount of material to be passed in connection with these rollers, burring is more efficient and the output of the machine may be in- 1 first swift of 'a carding' engine.

55 In order that o'ur'invention'may be better understood vv we hereinafter describe a suitable means and apparatus for carrying same into effect. f 1 v In a usual apparatus there are what are known as lickers or taker in rollers (four in number) 5' arranged in line, the wool or like being fed to the first one and taken from thelastone and conducted to the swift or first cylinder where card ing takes place in usual manner.. H

In order to attain-our object, in aconvenie'nt 10 form, it can be assumed that the first and last lickers of a usual apparatus are not disturbed, the material being fed to the first one L in usual manner. Above the first licker L we mount what is known as a divider D, which revolving slowerv than the licker L takes a portion of the material and delivers it to a licker L which we term the first top licker, with a tightener roller T, between D and L Above the divider D and licker L we mounta divider A. A bur roller B is provided below the lickerfL This licker. Y may with advantage beof the"Mo'rel'type, de-j livers its material to a second topj.lickerf L which preferably is also of the Morel type, a bur roller 13 being above L A brush C may operate between the first and sec'ond'top licker L and L to press the wool or like againsttthe licker.L andja divider A belowwill operate. on the two lickers L and L and whilst a bur roller may operate below the" divider A we do not in practicefind this necessary. A third divider member A is between the second top licker L and the end or'final ordinary licker L from which by a bottom divider A the .material is delivered to the swift S. This gives the upper courseof the material.

The lower course of the material is from the first main licker L to a first bottom lickerf L After the1icker L there :-is an assisting brush C operating from the licker L to licker, L and later orbelow a tightener roller T a lower bur roller 13? operates in connection with the licker L and is just clear "of a bottom divider'-A which co-operates between the first bottom licker L and the second bottom licker L bothof which are preferably of the Morel type, there being a bur roller B above, and a brush C will operate to press the wool or like against the licker-L The bottom divider may have abur roller below, but as mentioned above same is not in practice necessary. The second bottom licker L 'delivers its material to, the end'or final licker L 'and this completes the second path.

' Thebrush C before referred to may be dis 5's carded with some classes of material, but where hard heads or other undue compact material is present the brush C serves to prevent damage to the roller L from such hard matter. Whereas a usual type of apparatus comprises four lickers and eight bur rollers, we utilise in the form described six lickers and four bur rollers but it will be seen that in each path, there are four lickers, two being common to each of the paths.

It will be noted that the lickers or Morel cylinders L and L are adjacent and rotatable in opposite directions, as is the case with the lickers L and L The bur rollers B, B and 1-3 will each have scraper members of usual formation and these are shown at F and F and the guards G, G and G are provided to protect adjacent rollers against extracted burs falling or being directed thereon. It will be seen that the lower bur roller B is not provided with a scraper, the burs falling on to the floor below, but in the other cases the scrapers F and F are almost in the same vertical plane and the scraper F serves both the bur rollers B and B The licker L is driven from the swift S by a crossed belt and the lickers L and L are driven also from the swift by open belts. lhe licker L being driven from the licker L and the licker L is driven from the licker L by a crossed belt. Arrows in the drawing illustrate the direction of rotation of the various parts. All other driving arrangements are similar to those provided on a usual standard machine.

We find that by using duplicate adjacent Morel rollers operating in opposite directions and arranging the parts as hereinbefore described not only is the burring operation most efficient but a carding action takes place before the material is delivered to the swift this enables us to deal efficiently with long wools as well as short, and we find that the amount of wool taken out in the burring process is very much less than that taken out in usual processes.

What we claim is:

1. That method of treating wool and like material which consists in feeding and separating the material to be treated, separating the ribbon into upper and lower layers to form separated strips, subjecting each strip to the action of bur extracting rollers, and subsequently combining the material into a single body.

2. That method of treating wool and like material which consists in feeding and separating the material to be treated, separating the ribbon into upper and lower layers to form separated strips, subjecting each strip to the action of bur extracting rollers, subsequently combining the material into a single body, and subjecting the com bined body to a carding action.

3. That method of treating wool and like material which consists in feeding and separating material to be treated, separating the ribbon into upper and lower layers to form separated strips, maintaining said strips in separated condition, subjecting said separated strips individually to the action of bur extracting rollers, and subsequently combining said stripsto form a single body.

4. That method of treating wool and like material which consists in feeding and separating material to be treated, separating the ribbon into upper and lower layers to form separated strips, maintaining said strips in separated condition,

5.
